US and Australian scientists have reported that more lung cell types can be infected by SARS-CoV-2 than previously thought, including those without known viral receptors. [ + ]

Researchers have developed a diagnostic platform that uses similar techniques to PCR, but within a handheld device rather than several benchtop machines. [ + ]

People who gain excess weight from their 20s onwards have less healthy hearts by their 60s, while those with healthy diets are more likely to be well-functioning at age 70. [ + ]

Angelman syndrome is a rare genetic disorder characterised by poor muscle control, limited speech, epilepsy and intellectual disabilities. [ + ]

Researchers have revealed that a wide range of PFAS (perfluoroalkyl substances) can permeate the skin barrier and reach the body's bloodstream. [ + ]

Scientists are potentially closer to an HIV immunisation regimen than ever before — one that could produce rare antibodies that would be effective against a wide range of HIV strains. [ + ]

Scientists have identified a gene which, when missing or impaired, can cause obesity, behavioural problems and, in mothers, postnatal depression. [ + ]

Researchers have discovered a highly promising replacement for polyethylene glycols (PEGs), which are considered almost indispensable in the pharmaceutical and medical fields. [ + ]

An international research team has assembled a 3D reconstruction of the genome and chromosomal structures of a 52,000-year-old woolly mammoth. [ + ]

Astronomers have found compelling evidence for the presence of an intermediate-mass black hole — a 'missing link' from the early stages of galaxy evolution — just 17,700 light-years away from Earth. [ + ]

Biomedical engineers have been growing complex, functional 3D muscle tissue from stem cells in order to better understand and test treatments for an extremely rare muscle disorder. [ + ]

The new clock is so precise that it can detect tiny effects predicted by theories such as general relativity, even at the microscopic scale. [ + ]

US researchers have found that, in mice, a specific population of 'time cells' is essential for learning complex behaviours where timing is critical. [ + ]

The Australian-invented AI tool has the potential to reshape virtual screening in early-stage drug discovery and enhance scientists' ability to identify potential new medicines. [ + ]

The newly developed lymph node is implanted under the skin and is designed to teach immune system T cells to recognise and kill cancer cells. [ + ]
